[1] The Hierarchy Content Provider (Kai Sommerfeld 著, 版) https://www.openoffice.org/ucb/docs/ucp-ref/hierarchy-ucp.html

Each HCP content has an identifier corresponding to the following scheme:

vnd.sun.star.hier:/<path>

where <path> is a hierarchical path of the form

<name>/<name>/.../<name>

where <name> is a string encoded according to the URL conventions.

Examples:

vnd.sun.star.hier:/ ( The URL of the HCP Root Folder )

vnd.sun.star.hier:/Bookmarks/Sun%20Microssystems%20Home%20Page

vnd.sun.star.hier:/Workplace/Printers
